That was the deciding reason why I went with Oculus (that and the price reduction)
like enabling full-body tracking.
Sure, go for the inside out tracking for the headset, which would free up the sensors for body tracking.
You made the decision to buy an Oculus Rift now, based on the assumption that a future product of this company may offer a feature which clearly seems out of scope for the current product you just bought?
....so with this topic I beg Oculus with CV2, Microsoft with current gen, and Valve with CV2 to do not abandon the external sensor tech for the future, or to evolve the inside out tech to reach those results, because it's simply freedom of choice in movements.
p.s. Oculus please if possible let us use our old sensors with CV2 other then new ones if you are in plan to make a v.2.0 sensor.
